Copycat Do u do copy and paste all the time...and that's why your nick is copycat? ;) WELL, To me you sound like an undergarduate student( biology related major). If you are not, please disregard my posting. I am assuming this is an project given to you( I was given the similar project when I was an undergraduate long time back) and honestly you should be doing some literature review not browsing sajha every other minute to see if sombody replied your thread with an answer Its a learning experiment dear, and as we have the very true saying"Ki parera janincha ki padera janincha" and specially when you are in the feild of Biochem/ biology major, this is the only way. There is no alternative. My advice to you, 1.go to "http://www.ncbi.nlm.nih.gov/entrez/query.fcgi?DB=pubmed" 2.Type in "superoxide dismutase" 3. there are hundreds of paper,narrow down the search 4. Just scan thro' the title of the papers 5. scan thro' the Abstract of the paper BOOOM ....there is your answer. Good luck :)
